遍历包含不同级别映射的接口映射

Question

So lets say I have a map of interface like this:

c := map[string]interface{} {
    "test":    test,
    "test2":   test2,
}

Assuming that test is a map[string]map[string]map[string]string and test2 is map[string]string.

How would I create a for loop that would enumerate each index of the map and would enumerate through each index's map also?

So far I have gotten:

func sanitize_map(m map[string]interface{}) map[string]interface{} {
    for k, v := range m {
    //Here is where I want to enumerate through the map of k
    }
    return m
}

No need for reflection; use a type assertion and pass the value back to your sanitize function

func sanitizeMap(m map[string]interface{}) map[string]interface{} {
    for k, v := range m {
        _ = k
        if v, ok := v.(map[string]interface{}); ok {
            sanitizeMap(v)
        }
    }
    return m
}
